Bug of the Week: Millipedes

We found some of these in the bottom of a potted plant we brought home from the nursery this week.

Although it has antennae, it definitely has too many legs to be an insect larva.

millepede2

In fact, you can see that it has two pairs of legs per body segment. That means it is a millipede.

Millipedes are often found in damp soil or rotting logs. Most feed on decomposing plant matter, so they are nature’s recyclers.

Millipedes do not bite or sting, and are relatively harmless. They do have the ability to emit various chemicals to defend themselves (depending on the kind), so it is best not to pick them up. Their main defense, however, is to roll up into a ball.

If you are interested in finding out more, Enchanted Learning has an information sheet with a nice drawing showing all the parts of a millipede.

Seed of the Week: Cottonwood Trees

Can you imagine, the seeds in the bit of fluff from last week’s mystery seed can grow into one of the tallest eastern hardwoods?

This is the eastern cottonwood, Populus deltoides.

The species name comes from the “deltoid” shape of the leaves.

Cottonwoods often grow near water.

They have deeply grooved, braided bark.

In the fall the leaves turn a gorgeous golden yellow.

Do cottonwoods grow where you live?
